60fps video playback on YouTube

[Chipango]

Is there some specific way of encoding videos so that YouTube does not change their framerate back to 30fps? I'm trying to upload 60fps videos but YT automatically changes them to 30fps after processing.

Here are some examples of 60fps videos on YouTube:

I've tried lots of different codecs, resolutions, bitrates, containers, but still cannot get the right configuration.

I hope someone can help me with this!
Thanks in advance.

Have you tried uploading 60 fps flv file? Downloading one of the files then uploading it yourself?

Yes. YouTube apparently does not accept .flv video files any more for upload. Whenever I uploaded a .flv (Flash Video) file, it said "Failed (unable to convert video file)".

I'm having issues with this as well, I have an MP4 file that I've run through VDub (captured from a DV camera) that runs at 60 fps on my computer, but Youtube destroys the quality (evident here http://www.youtube.com/watch?v=suJCWkgwBr8). Anyone have any advice?

What did you upload ? The original footage or something else like a deinterlaced intermediate?

Youtube re-encodes everything at a limited bitrate, so it will destroy the quality . It's supposed to.

sorry double post

I used VDub's deinterlacing with the yadif algorithm and preserved the doubled framerate, then exported it as a 16:9 MP4 at full available quality. I suppose I care more about the framerate than the actual quality of the video in this particular case.

AFAIK, youtube doesn't allow 60fps

The examples above are all old, before the changes at youtube

Also notice they are all tiny like 320x240 and less than a few MB

Damn, oh well.
